摘要:
测控系统是航天工程不可或缺的重要组成部分,其导航通信能力在深空探测任务中尤为重要.深空探测任务远距离、长延迟、弱信号、易中断条件下高精度导航测量和高速可靠数据传输始终是深空测控技术需要重点解决的问题.围绕这些问题重点介绍了在天线组阵、再生伪码测距、连接端站干涉测量、相位参考干涉测量和容延迟网络等一系列新技术方面开展的研究工作和部分成果,可以看到,这些成果的应用将丰富深空测控技术手段,在未来更复杂、更遥远的深空探测任务中将会发挥重要作用.

Abstract:
The TT&C system is an indispensable part of deep space exploration project with its navigation and telecommunication performance being the key factor for mission success and science output. In condition of faraway distance, long delay, feeble signal and easy discontinuity, developing and applying a series of deep space TT&C new technologies, such as antenna array, regenerative pseudo-noise (PN) ranging, connected-element interferometry, phase-referencing interferometry and delay-tolerant network, can provide high precision navigation methods and high rate data transmission capabilities for future deep space exploration missions.
